IMPROVEMENT 1N ExoAvA-rons.

Specification forming part ofLetters Patent No. 43,392, dated July 5, 1864.

To @ZZ whom it 1v1/ty concern:

Beit known that I, DANIEL CLOSE, of Harmonsburg, in the count-y of Crawford, State of Pennsylvania, have invented a new and Improved Excavator; and I do hereby declare that the following is a full and exact description ofthe same, reference being had to the accompanying drawing and the letters of reference marked thereon.

Figure l is an inside view ot' my invention, one-halt' of the same of likel construction being removed so as to better show the same.

My excavator is constructed in its general form like a common two-horse wagon. A is the hind wheel,77 and B the fore wheel,7 thereof. rlhe hind wheel, A, has a very broad tire, from one foot to any desired width, as shown at A, Fig. 4. Between the spokes of this hind or excavating wheel are bolted the elcvators7 l 2 3 4 5 6 7 S 9 10 11 12 13. These elevators may be of any proper shape and size to best suit the size of the machine and the kind of soil to be excavated. In the drawings they are represented like a common scoop. These elevators extend through the thickness ofthe wheel. The open end of the elevators are on the inside of the wheel, while the outer ends are closed.

F is a plow, with the back end of the moldboard7 bent toward the wheel A, as shown at Fig. 4, so that the excavating-wheel revolves so near to the mold-board as to prevent any dirt escaping between them. rIhis plow F is bolted on a lever,7 D, which lever is suspended from the wagon-bled sill 7 C by a joint at K.

E is a semicircular guide passing through the clasp L, which serves to keep the lever D steady when the same is raised or lowered by means ofthe chain H and the lever G. This lever G is kept in any desired position by means of the iron circle I, which is notched on the inside, so as to receive and hold the lever G. By means of this lever D and the chain H and the lever G the plow can be raised and lowered at pleasure.. It can be drawn out of the ground, or adjusted so as to make the furrow of any desired depth.

Fig. 2 shows the plow F lowered down to near the position while excavating.

M M, Fig. 2, is a side view ot' the dirt-box as the plow enters the earth. The dirt is kept in the plow-i. e., between the plow F and the wheel A, and as this wheel revolves the excavators become filled with dirt., and by the revolution of the wheel A the dirt is carried up and emptied into the dirt box M M.

Fig. 3 is a top view of the dirt-box, showing the construction ot' the bottom for unloading the dirt.

N O are two valves as large as the whole bottom of the dirt-box. A rope,P, is attached to the valve N and passes under the valve O, and around a pulley, R, on the bed sill C, or any other suitable place. It then passes forward and is attached to a lever like the lever G, or any other obvious mechanical device. 'Ihe valves N and O are hung on pins s s .ss, so that when the rope P Pis slackened the weight ofthe dirt opens them. Then the rope P P is pulled, the valves are closed.

Fig. 1 only represents one half of my excavator. The other halt' is constructed exactly like the half described, except that there is only one dirt-box to two excavators and plows, the box being between the wheels, they emptying into it from each side.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is as follows, to wit.:

The dirt-box M M, with the valves in the bottom N O, constructed as described, in combination with the plows Fand elevators A, the whole when combined for the purposes set forth, and constructed as described.

DANIEL CLOSE.
